I will post a few pix tonight, but I used 2 X 2 aluminum angle, about two inches long, cut out to clear the manifold. I used the front, or hole closest to the side drivers side of the car to attach it.
That allowed the bend in the cable to be a bit more gentle, and let me alter the linkage to my advantage. On the hump inside the car, I used to existing bracket that came from a ford pinto. However, if I had to make one, I would use 2 x 2 x 2 channel. Bending the sides outward would allow attachment to the hump, at the correct angle to mount the pedal.
Pix later tonight.
